1. Yintoni i-Hot Rolled Steel Material Grades
Intsimbi yintsimbi exutyiweyo equlethe isixa esincinci sekhabhoni. Iimveliso zentsimbi ziza kwiindidi ezahlukeneyo ngokusekwe kwipesenti yekhabhoni ezinayo. Iindidi ezahlukeneyo zentsimbi zahlulwe ngokwemixholo yazo yekhabhoni. Iindidi zentsimbi eziqengqelekayo ezishushu zahlulwe ngokwamaqela ekhabhoni alandelayo:
Intsimbi ekhabhoni ephantsi okanye ethambileyo iqulethe i-0.3% okanye ngaphantsi kwekhabhoni ngokomthamo.
Intsimbi yekhabhoni ephakathi iqulethe ikhabhoni eyi-0.3% ukuya kwi-0.6%.
Iintsimbi ezinekhabhoni ephezulu ziqulathe ikhabhoni engaphezulu kwe-0.6%.
Izixa ezincinci zezinye izinto zokudibanisa ezifana ne-chromium, i-manganese okanye i-tungsten nazo zongezwa ukuvelisa ezinye iintlobo zentsimbi. Iintlobo ezahlukeneyo zentsimbi zibonelela ngeempawu ezahlukeneyo ezifana namandla okutsalwa, ukuguquguquka, ukuguquguquka, ukuqina, kunye nokuqhuba kobushushu kunye nombane.
2.Umahluko phakathi kweNtsimbi eQokelelweyo eshushu kunye neNtsimbi eQokelelweyo ebandayo
Uninzi lweemveliso zentsimbi zenziwa ngeendlela ezimbini eziphambili: ukuqengqeleka okushushu okanye ukuqengqeleka okubandayo. Intsimbi eqengqelekayo eshushu yinkqubo yokusila apho intsimbi igxothwa khona kubushushu obuphezulu. Ngokubanzi, ubushushu bentsimbi egxothiweyo eshushu budlula i-1700°F. Intsimbi egxothiweyo ebandayo yinkqubo apho intsimbi igxothwa khona kubushushu begumbi.
Kubalulekile ukuqaphela ukuba zombini intsimbi eqengqelekayo eshushu kunye nentsimbi eqengqelekayo ebandayo ayizontlobo zentsimbi. Ziindlela zokwenza izinto ngaphambi kokwenziwa ezisetyenziswa kwiintlobo ngeentlobo zeemveliso zentsimbi.
Inkqubo yentsimbi eqengqelekayo eshushu
Intsimbi eqengqelekayo eshushu ibandakanya ukwenza nokuqengqa iislabhu zentsimbi zibe ngumcu omde ngelixa zifudunyezwa ngaphezu kobushushu bazo obufanelekileyo bokuqengqeleka. Islabhu eshushu ebomvu inikwa ngothotho lwee-roll mills ukuze yenziwe kwaye ilulwe ibe ngumcu obhityileyo. Emva kokuba igqityiwe ukwenziwa, umcu wentsimbi upholiswa ngamanzi kwaye uboshwe ube yi-coil. Amanqanaba ahlukeneyo okupholisa amanzi aphuhlisa ezinye iipropati ze-metallurgical kwintsimbi.
Ukulungisa intsimbi eshushu eqengqelekayo kubushushu begumbi kuvumela amandla angakumbi kunye nokuguquguquka.
Intsimbi eqengqelekayo eshushu idla ngokusetyenziselwa ukwakha, imizila kaloliwe, isinyithi, nezinye izinto ezingadingi kugqitywa okunomtsalane okanye iimilo ezichanekileyo kunye nokunyamezelana.
Inkqubo yentsimbi eqengqelekayo ebandayo
Intsimbi eqengqelekayo ebandayo iyafudunyezwa kwaye ipholiswe njengentsimbi eqengqelekayo eshushu kodwa emva koko iqhubekeka isetyenzwa kusetyenziswa i-annealing okanye i-temper rolling ukuze kuphuhliswe amandla aphezulu okutsalwa kunye namandla okuvelisa. Umsebenzi owongezelelweyo kunye nexesha lokucubungula longeza kwiindleko kodwa kuvumela ukunyamezelana okusondeleleneyo kwaye kubonelela ngeendlela ezahlukeneyo zokugqiba. Olu hlobo lwentsimbi lunokugqitywa okuthambileyo kwaye lusetyenziswa kwizicelo ezifuna imeko ethile yomphezulu kunye nokunyamezelana okulinganayo.
Ukusetyenziswa okuqhelekileyo kwentsimbi eqengqelekayo ebandayo kuquka iindawo zokwakha, ifenitshala yesinyithi, izixhobo zasekhaya, iindawo zeemoto kunye nokusetyenziswa kobugcisa apho ukuchaneka okanye ubuhle kufuneka khona.
3. IiBanga zeSteel eziShushu eziSongiweyo
Intsimbi eqengqelekayo eshushu iyafumaneka kwiindidi ezahlukeneyo ukuze ihlangabezane neemfuno zeprojekthi yakho. I-American Society for Testing and Materials (ASTM) okanye i-Society of Automotive Engineers (SAE) imisela imigangatho kunye neendidi ngokwesakhiwo kunye nobuchule besinyithi ngasinye.
Iindidi zentsimbi ze-ASTM ziqala ngoonobumba u-“A” omele iintsimbi zentsimbi. Inkqubo yokubeka i-SAE (ekwaziwa ngokuba yi-American Iron and Steel Institute okanye inkqubo ye-AISI) isebenzisa inani elinamanani amane ukuhlela. Iindidi zentsimbi yekhabhoni ezicacileyo kule nkqubo ziqala ngedijithi eli-10, zilandelwe ziinombolo ezimbini ezibonisa uxinzelelo lwekhabhoni.
Ezi zilandelayo ziintlobo eziqhelekileyo zentsimbi eqengqelekayo eshushu. Nceda uqaphele ukuba ezinye iimveliso zifumaneka kwiindlela eziqengqelekayo ezishushu nezibandayo.
